You can desaturate a photo and then restore color selectively using the History Brush Tool in Photoshop. It is very easy to do and can be done in any version of photoshop.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOPCVMA_mh0lg6_X2MPQD0hyphenhyphen7f8PF0PjeUmnIpZHrX7r4-jw-n1020UAstWUgWJ2ca_bv4WTjpTnO_3l9WQn3FAmouE8kByr7Rrxu3OtdKY91ZQlo5mldNvJImrb3tIhkUxP9KXSkgjHC_/s400/BW+and+Color.jpg)

I took this snap of the Maidan in Kolkata with my mobile phone camera while going to office. I desaturated the image then restored color in parts with the History Brush Tool.
